VALVE Application filed December I, 1987. Serial No. 2889432.

tion with plumbing fixtures. A valve of this kind is customarily used in so-called builtin installations i. e. it is mounted behind a wall,l the handle mechanism projecting through the wall to the front thereof, and

independent stop valves are employed to cut off the supply of water from the valve to enable its operating mechanism or' valve member proper to be withdrawn from its casing for repairs or replacement without spilling of water.

It is theprincipal object of the invention to eliminate the aforesaid independent stop valves and to supply a valve of this character with means which automatically prevent the spilling of water by simple removal of its operatlng mechanism.

Another object is the arrangement of the component parts of the valve in such a way as not to restrict unnecessarily the full area. of its water passages.

A further object is to enable its component parts to be easily removed, readily adjustable, and to provide a valve which can be manufactured at a comparatively smallcost.

Still further objects and advantages of the invention will become apparent in the following specification and the accompanying drawings in which Fig. 1 is a vertical longitudinal sectional view through a valve showing a preferred embodiment of the principles of the invention, the valve being shown in an open position while water is passing therethrough;

Fig. 2 is a similar sectional view, but with the operating mechanism and its main valve member removed ands its auxiliary valve member shutting off the valve passages, preventing the spilling of water;

Fig. 3 is a detail horizontal sectional view along the plane of line 3-3 in Fig. 1; and

Fig. 4 is a plan view of a removable seat for the main valve member.

Like characters of reference denote similar parts throughout the several views and the following specifications.

10 is a. valve housing having an inlet end 11 and an outlet end 12; both interiorily threaded to receive, respectively, a pipe 13 and a pipe 14. 15 is a bridge or partition separating the housing 10 into an inlet chamber 16 and an outlet chamber 17. 18 is a cylindrical extensionof the outlet chamber projecting partly through a wall 19, its end being interiorly threadedat 20.

Bridge 15 is threaded preferably in axial alignment with cylindrical extension 18 to receive a sleeve 21 having a circular flange 22, resting fluid-tightly against the top of the bridge, and an annular seat portion 23 immediately above it. 24 is a similar seat portion immediately below the threaded part of the sleeve 21 and projecting into the inlet chamber 16. Interiorly, the sleeve 21 is preferabl square-shaped through part of its lengt at 25.

26 is a bonnet screwed into the threaded inner portion 20 of extension 18 of the housing 10. Bonnet 26 is cylindrically extended into the outlet chamber 17 at27 and interiorly threaded at 28 to receive a valve spindle 29. 30 is a gland around the outwardly projecting part of the spindle 29 screwed into the outer end of the bonnet to compress packing 31 around the spindle to prevent leakage of Water in the manner well known in the art. 32 is an escutcheon to cover bonnet and gland projecting from the wall 19, which escutcheon is held against the wall by a nut 33 adjustabliy threaded upon the gland 30. The outwar ly projecting end of spindle 29 is provided with a handle 34. 35 is a central portion of the spindle threaded to correspond with part 28 of the bonnet. 36 is a bore through the bonnet forming a shoulder with the threaded part 28 to function as a sto for the threaded portion 35 of the spin e, as will be explained more in detail hereinafter. The lower or innermost end of spindle 29 is bored out at 37 to receive a main valve member 38, substantially diskshaped at 39, and provided with a tapering shank 40 adapted to project into bore 37 of the spindle 29 the side walls of which are crim ed together at 41 to hold the valve mem er 38 loosely to the spindle. The side of the disk 39 facing the valve seat 23 of sleeve 21 isrecessed slightlyto receive a washer 42 of fiber, vulcanized rubber, or other suitable material. 43 is a stem adjustably screwed into the underside of the disk 39 havin a relatively long threaded ortion 44, an 45 is a lock nut holding the fiber washer 42 against the disk 39 and by its clampin portion 44 t e stem 43 in thead usted posltion.

The lower end of valve housing is ex-v tended at 46 coaxiallywith sleeve 21, spindle 29 and stem 43, and has a'bore 47 extending partly therethrough, formin a socket 48. 49 is an auxiliary or secon ary valve member consisting of a disk 50 recessed to receive a' washer 51 of fiber or the like, held within the recess by means of a screw 52, and a stem 53 snugly guided within the socket 48. Stem 53 is flattened at 54 to revent its stickin within the socket. 55 1s a spring within t e socket exertin an upward pressure against the bottom 0 the stem 53. The extreme end of stem 43 of the main valve member 38 is adapted to engage the secondar valve member by contact with the top 0 the screw 52.

The operation of the device is as follows: While the valve is in the open position shown in Fig. 1 water is admitted through inlet pipe 13, inlet chamber 16, through valve port in sleeve 21 into the outlet chamber 17 and outlet pi e 14. While the valve is thus openi) the t readed part 35 of its spindle 29 a uts the shoulder formed by bore 36 which serves as a fixed stop for the spindle; the stem 43 contacts with head of screw 52 of'the secondary valve and keeps the disk 51 away from its seat 24 sufliciently far to permit the full volume of water to pass between it and the seat; the s ring 55 assisted by the force of the flow of t e water keeps the disk 51 against stem 43. In order to close the valve, spindle 29 is screwed down in the usual manner until disk 42 rests upon raised valve seat 23 when theflow of liquid is interrupted. While thus screwing down main valve 38, stem 43 depresses secondary valve 49 proportionately. There is, however, clearance provided for between the underside of disk 50 and the bottom of the inlet chamber 16 when the disk 39 is in the closed position, so thatwasher 42 will form a fluid tight seat upon sleeve 21.

Should it be desired to' withdraw the spindle 29 and the main valve 38 for inspection or repairs, the escutcheon 32 is first removed, and then the bonnet 26 together with spindle 29 and valve 38. As the stem 43 of the main valve is gradually withdrawn, sprin 55 raises the secondary valve 49 until su cient withdrawal of the stem permits the washer 51 to rest tightly against the lower valve seat 24 of sleeve 21, thus effectively closing the valve port fluid tightly.

* ly and no This eliminates the use of independent stop valves to shut off the flow of water when the main valve members are withdrawn. The secondary valve works entirely automaticalparticular skill is required to replace the main valve. The position of the secondary valve between its seat and the action against the threaded What I claim as new, is:

1. A valve structure for the purpose specified, comprising a housing, a partition in the housing dividing it into an inlet chamber and an outlet chamber, a sleeve removably secured to the said partition, having means at its interior to screw itinto the partition and a seat projecting into the inlet chamber at one side and a seat projecting into the outlet chamber at .the other side, a bonnet screwed into the outlet chamber of the housing in alignment with the said sleeve, a valve spindle adapted to be reciprocated within the bonnet, a main valve disk, a main valve disk having a shank of substantially inverted conical shape above its main portion, the said shank being closely fitted into a cylindrical recess at the end of the said spindle, the walls of ,the said recess being imperforate and adapted to be crimped together to secure the said disk rotatably to the said spindle, the said disk being adapted to contact with the seatof the sleeve projecting into the outlet chamber, a' secondary valve disk having a stem slidably secured within a socket at the bottom of the inlet chamber and in alignment with thefsaid sleeve and being adapted to contact with the seat of the sleeve projecting into the inlet chamber, a spring within the socket forcing the said secondary valve disk toward its seat, and a stem forming part of the said main valve disk projecting through the said sleeve and in contact with the said secondary valve disk to forcethe same away from its seat.

2. A valve'structure for the purpose specified, comprising a housing, a partition in the housing dividing it into an inlet chamber and an outlet chamber, a'sleeve screwed into the said partition, having means at its interior to screw it into the partition and a raised seat projecting into the inlet chamber at one side and a raised seat projecting into the outlet chamber at the other side, a bonnet screwed into the outlet chamber of the housing in alignment with the said sleeve, a

valve disk having a shank of substantially above its main orinverted conical shap):

ing closely fitted into tion, the said shank a cylindrical recess at the end of the said spindle, the walls of the said recess bein imperforate and adapted to be crimpe together to secure the said disk rotatably to the said spindle, the said disk being adapted to contact with the seat of the sleeve projecting into the outlet chamber, a secondary valve disk having a flattened. stern slidably secured within a socket at the bottom of the inlet chamber and in alignment with the said sleeve and being adapted to contact with the seat of the sleeve projecting into the inlet chamber, a spring within the socket forcing the said secondary valve disk toward its seat, and a stem adjustably secured to the said main valve disk projecting through the said sleeve and in contact with the said secondary valve disk to force the same away from its seat.

In testimony whereof I have hereunto set my hand.
